Probiotics perform an important function. They provide friendly bacteria to our digestive tracts to keep things running smoothly.

These friendly bacteria help to keep a proper flora balance, preventing harmful bacteria from taking over and creating assorted health problems.

Taking probiotics enhances our immune systems, protecting us from infection. Pregnant women benefit from taking probiotics, and so do babies in the womb.

Babies receiving probiotics early in life are less likely to suffer from eczema. Autistic children may have better brain function. Individuals needing to take antibiotics will preserve their healthy flora by the addition of probiotics.

Dr. Andrew Weil recommends Bacillus coagulans (BC-30) or Lactobacillus GG. "The dose is one tablespoon of the liquid culture or one to two capsules with meals unless the label directs otherwise. Always check the expiration date to make sure that the bacteria these products contain are alive and in good condition and look for probiotics with 'colony forming units' (CFUs) in the billions. After you buy, be sure to protect your supply from heat, moisture, and air."
